Excitation of the symmetry forbidden bending mode in molecular photoionization

Abstract

We present results on the energy dependence of the vibrational branching ratio for the bending mode in CO2 3sigmau-1 photoionization. Specifically, we determine the v+ = (0,1,0)/v+ = (0,0,0) intensity ratio by detecting dispersed fluorescence from the electronically excited photoions. The results exhibit large deviations over a very wide energy range, 18
